nppl ication fl led September e, 1918. serial No. 252,939.

To all whom it may concern 7 Be it known that l I, Rnno'nrrr BECKER, a citizen or the United States, residing at Roselle Park, in the county of Union and State'of New Jersey, have invented certain .new and useful Improvements in Work 7 IIolders,of which the followingis a specification, reference being had therein to the accompanying draw ngs.

Th1s invent on relates to an lmprovement in means for sewing the bows of hat ribbons to a hat. j

V The objects of the invention are, to provide a work-holding means by which the edge of the upper or outer limb of a ribbon bow may, be deflectedto'one side, while'the lower limb is held-and stitched tothe hat. which means may be readily moved out of the way when desired and automatically held in inoperative position, to provide a plurality of such means, one or all of which maybe used as desired, to provide a'guide or gage for cooperation with the deflectin means,

and to provide shiftable means onthe workarm in connection with the work holding means and guide for properlylocating the work. I Y

The invention comprises a work-holder including a work-support movable on the work-arm of the machine, said work-support having an elongated needle aperture,work' gripping and detaining means adjacent said aperture, a'pivotally mounted work-guide and gage adjustabletoward and from said aperture, an overhanging pivotally mounted arm carried by the work-supportand yieldingly pressed toward the same, and inde pendently movable work-clamping and defleeting fingers carried by said arm, said fingers when inoperative position extending toward the worksupport adjacent the stitch- 'ing point. Means are provided for holding reciprocating movementby suitable means, 7

such as that shown by patent to C M.'Horton, No, 1,051,998,

, Reierring to the accompanying drawings, Figure l is aside view of a sewing "machine with the work-holder attached. JFig. is" a hor on a sectio taken a o the work-aimfFig-iii is aperspective'view of dated February 4, 1913.

' In the drawings 1 represents the base of a machine, from which projects a work-arm Patented Augi24,

2 and anbvenhanging arm-3, the latter'arrn carrying a reciprocating ne'edlej-barf and needle 5. The work-holder comprises a work-support formed of the plates G and 7 secured together and slidable in a groove in the top of the work-arm. Near the front end ofthe work-support an elongated needle aperture 8 is provided, andfadjacent said aperture' short projecting work-gripping points 9are located. The outer portion o plate 6 is slightly inclined upwardly and outwardly. A work-guide and gage is pivotally mounted onthe work-support the screw 10, which screw also serves to secure a springfing'erll adapted to engage a recess 12 in the work-support when the guide is in operative position. The guide is formed in two parts 1 3 and 14, the part 14 being slida'ble in.dove

tail grooves formed at the edges of the part 13, and the two parts being secured in adj usted position by ascrew 15 passingthrough a slot 16 in the part 14andthreaded into the. part 13; The end'of the part 14 nearestthe needle-aperture is turned up'as at 17lto form an outwardly inclined work-guide and gage. An upright 18 is secured to theplate 7 and carries anextension 19' at the top' .of whi'ch an arm 20 is pivotally'mounted at 19. A coiled spring 20 surrounds the pivot of the arm and has one end secured in any desired manner to the extension 19 and the other endfbearing against thetop of arm 20, thereby yieldingly pressing said arm downwardly. The arm 20 passes through a slot in the headof the over-hanging arm 3 and at its forward endcarriesa downwardly directed extension 21. (Fig; 3) having an overhanging flange .22 at its upper end. Mounted to slide in the head of arm 3 is a j rod ,23. having a collar 2 1 secured thereon which'engages' beneath the flange 22 Of'arm 20. A second collar 25'is secured to the upper end of rod 23, and alever 2 6 fulcrumed on the arm 3 has a forked end 27 engaging beneath the collar 25. Connected to the opposite end of lever 26 is a link 28 leadin to a pedal or' other operating means. ecured to the lower end of extension 21 is a horizontal arm 29 having down- W'ardly directed lugs '30, said arm together lugs '30 the arm 29 has a recess inwhic'h" With the extension 21 and arm 20 forming a pivotally mounted frame. Between the the 'needle-barandneedle move. 1 k Pivotally connoctedto adjacent sides of the lugs 30 are inwardly curved fingers "31 having out-turned ends 32. At the end adjacent its pivoteachfinger 31 has one rounded corner 33 and one squared corner 34 (Fig.

The rounded corner permits the finger 31 to be swung upf n one d rectlon into :a

I horizontal position, but movement upward in the oppositedirection is prevente dby engagment of tlie corner 34 with the arm :29. F lat springs are secured, to the arm 29 and the free end of each spring isadapted to engage-one'sideor the other ofa corresponding: corner 341 dependent upon whether thefinger 31191111 a vert cal or horizontal position, to thereby yieldingly hold the finger in either position Afvertica-l rod 36 pro ee.ts

The fingers 31,,are lnserted be- .of the hat crownrand 1 In operation the fingers '31 are raised vagainst the pressure of sp'ringflOf by opera- 'tion of lever 26, either manually or through the link 28,-;andthe work placed in-positi'on,
